Using your inkey function you could:

Code:
void number_input() {
   inkey((t_input.pstring)[0]);
   result= str_to_int((t_input.pstring)[0]);
}
 
//in your other function
for (i = 0; i < 3; i++) {
   number_input();
   while (proc_status(number_input)) {
      wait(1);
   }
   loc_i2 = result;
}


the reason for this is that inkey will internally exicute a wait and will cause your function to return to the caller.
